Side Mirror Turn Signals

I appreciate all the enhancements GM made in the Gen2 Volt. Two features they removed are a bit of a head scratcher though. 1. Homelink (I'll add this myself at some point) and 2. Turn signals integrated into the side mirrors. I really like how these look in the Gen1 Volt, and would like to figure out options to add them to my Gen2.

Anyone know of another GM side mirror which includes turn signal lights that could be easily swapped with the Gen2 Volt mirrors, or anyone tried to retrofit an LED strip or something into the Gen2 side mirror?
